Unfortunately the two companies that actually build and fly electric
pumped rockets don't publish much of anything about them. But the
cycle is simple enough that they follow basic models fairly well.

Yes, their are many ways to do a job but sometimes easy to loose sight of the
original point and get off on a tangent. KISS comes to mind.
Scaled topping cycle engines is cool but still like to see that eclectic pump
scaling analysis.

If you've gone to the trouble of building a gas generator and a turbine,
there's no obvious reason to interpose a generator and a motor between it
and the pump -- either a direct shaft connection or a gearbox is a lot
simpler, and likely to be a rather lighter way to handle that much power.
